This is how to connect to wiihacks iRC with ChatZilla. Much Shorter than mIRC but Chatzilla is only for Firefox.
Open Firefox and download Chatzilla
[Only Registered Users Can See Links. Click Here To Register]
Press Add to Firefox then A Pop up should appear, press Install Now. Then Restart Firefox.
Now that firefox has restarted, in the Address Bar, type irc://irc.uicn.net/wiihacks and press enter.
Give it some time and it should connect to the irc.
Next Press the little arrow next to the box that says User in the lower right corner (In my case, it says ShadowSonic2)
Press Change Nickname and enter your forum nickname and press Ok. Remember to register your nickname and follow the rules.
If you want the channel to start automatically when you open ChatZilla, right click the #wiihacks tab and select Open Channel At Startup.
Now instead of typing the address of the iRC, all the time. When you open Firefox, press Tools and then Chatzilla. It should automatically conenct you to WiiHacks iRC.
